H EATI NG-STOVE.

SPECIFICATION forming part of Letters Patent No. 254,660, dated March 7, 1882.

Application iiled November 28, 1881. (No model.)

To all whom it may concern Be it known that I, OLIVER B. KEELEY, a citizen of the United States, residing in Spring City, Chester county, Pennsylvania, have invented certain Improvements in Heating- Stoves, of which the following is a specification.

The main object of my invention is to increase the air-heatin g capacity of that class of stoves known as parlor-heaters, a further object being to accomplish this result without interference with the illuminating qualities of the stove.

In the accompanying drawings, Figure 1, Sheet l, is a longitudinal vertical section of a heating-stove with my improvements; Figs. 2 and 3, Sheet 2, sectional plan views of the same on the line -1 2, but with the movable parts in different positions; Fig. 4, a sectional plan on the line3 4, Fig. l 5 and Fig. 5, a transversevertical section of part of Fig. l, showing modifications of part ofthe invention. The views on Sheet 2 are on a smaller scale than Fig. l.

Ais the casing of the stove; B, the combustion-chamber; D, the magazine; and E, an air-heating chamber formed by an annular casing surrounding Vthe upper portion of the casing of the com bustionehamber B, this air-heatingchambercommnnicatingabovewithadrum, G, from which the hot air is cond noted by suitable pipes to a room or rooms above that in which the stovez is situated.

At the back of the stove are two lues, a b, communicating with each other at the bott-om through a partitioned chamber, d, at the base of the stove, the upper end of the flue a communicating with the combustion-chamber B, while the upper end of the iiue b communicates with the pipe leading to the chimney, so that when the stove is in operation the products of combustion descend the flue a, traverse the chamber el, and ascend the flue b prior to their escape. There is the -usual dampered opening, c, whereby direct draft from the combustion-chamber to the chimney is afforded in starting the lire.

Between the casing A of the combustionchamber and ash-pit of the stove and the casing I of the lues a b intervenes a chamber, made in two parts, J J', the upper part, J, of

the chamber being contained between dan ges f and g on the casing A, and being open at both sides, while the lower` portion, J', of the chamber-that is, the portion below the iiange g and between the casings A and I is partially closed at the sides by' ornamental work of such a character as will not interfere with the free entrance of airto said portion J of the chamber, communication between the two portions of the chamber being afforded by an opening, t', in the ange g, and communication between the portion J of the chamber and the hot-airchamberE being permitted by an opening, i.

In the ian ges f and g are formed guides for two segmental shields, M, which can slide freely in their guides and can be brought forward, as shown in Fig. 2, so as to partially inclose the casing of the combustion-chamber of the stove, this portion of the casing being provided with the usual illuminating doors or windows, m. When thus brought forward the front ends of the shields abut against radial ribs p on the stove-casing, and the direct radiation of heat from the inclosed portion of the stove-casing into the room in which the stove is situated is prevented, the chambers formed between the casin g of the stove and the shields M serving to heat air admitted thereto through openings s in the bottoms of the shields, the air, when heated, being discharged into the chamber J, and nding its way thence through theopeningt" and upward into the hot-airchamber E. Instead of taking this course, however, the air may ascend directly into the chamber E through openings t in the flange f, as shown in Fig. 4, and, if desired, the shields M may be closed at the bottom, openings for the admission of air in this'case being made in the flange g, as shown.

When it is desired to expose the casing of the combustion-chamber for the purpose of radiatin g heat directly into vthe room,theshields M are moved back until they occupy positions in the chamber J, as shown in Fig. 3.

Shields to partially inclose the casing of the combustion chamber have been heretofore used, and are shown in T. J. Coulstons Patent, No. 104,274, dated June 14,1870; butsaid shields have been made in the form of continuous segments of sheet or cast iron, and when IOO drawn forward such shields obstruct the view of the re through the illuminating-windows m of the stove-casing, and thus impart a cheerless appearance to the stove.

The shields. M in my improved stove have glassl or mica covered illuminating doors or windows n, so that the view of the rire is not obstructed when said shields are drawn forward. The form ation of the glass or mica covered openings in the shields is also of advantage in reducing the area of the metal portion ofthe shield, the mica radiating heatinto the room more readily than the iron, so that the temperature of the latter, when the shields are drawn forward, is not reduced to such an eX- tent as when imperforate shields are employed.

rIhe mica-windows also reduce the weight of the shields, and thus permitthem to be moved with less effort than the usual shields.

I claim as my inventionl. The combination of the casing A, hot-air chamber E, ue-casing I, and the heatingchamber made in two parts, J J separated by the ilange g, as set forth.

2. The combination of the hot-air chamber 25 E, the combustion-chamber B, the flue-casing I, the airheating chamber J between the uecasing and the casing of the combustion-chamber, and the shields M, adapted to form with the stove-casing air-heatin g chambers oom- 3o municatin g with the chamber J, as set forth.

3. The combination or" the stove-casing having illuminating doors or windows m, with the sliding shields M, having mica-covered openings u formed therein, as and for the purpose 35 specified. v In testimony whereof I have'signed my name to this specification in the presence of two subscribing witnesses.

OLIVER B. KEELEY.
